Large Milkweed Bug

Large Milkweed Bug
I know that most of you will not enjoy this.  I'm sorry.  I photograph what I like not what my viewers like.  That is probably why I don't have followers.  This is an image stack at 2X.

Large Milkweed Bug
This one is at 10X.

Large Milkweed Bug
I think I have mentioned previously that this insect's required food is the sap from the seedpods.  The one in the top left center is a larva.  Can you notice the wings, unformed,  It is near moulting, climbing out of its skin, to become like the larger insect near the center.

Large Milkweed Bug Exuvia
This is what they leave behind after moulting.  It is called an exuvia.  As I write the Large Milkweed bugs are still on the milkweed plant.  It is October 3, 2019.

Large Milkweed Bug Larva
I recognize most the insects visiting the milkweed because I visited the milkweed daily while I was at the nature center.  I started because I was interested in the Monarch Butterfly and its caterpillar.

Narsarsukite



Narsarsukite
Narsarsukite is rare.  This sample comes from Jones_Mill_Quary_Magnet_Cove_Arkensas.  Its colors can be:  Yellow, yellowish-white, grayish-white, honey-yellow, tan, greenish-yellow. 

Narsarsukite
This is a stack using Sigma 105mm Macro mounted on 68mm of extention.

Narsarsukite
This could be the greenish-yellow version of Narsarsukite.  Its formula is:  Na4(Ti,Fe)2[Si8O20](O,OH,F)2 

Narsarsukite
This may be the best if not the only view of conventional Narsarsukite on the sample.  I was reading at Excalibur Mineral Corporation site and they mentioned some samples of narsarsukite that contain needle like crystals such as the ones around these crystals.  They may be elbaite.

Anatase



Anatase
It as been some time since I showed Anatase.  This is a new, to me, sample:  Anatase_Poudrette_Qy._Mt._St._Hilaire_Canada.  I shot this with a Pentax 200mm mounted on 68mm with a nikon 10x objective.

Anatase without the Extention
This is the same setup minus the 68mm extention. 

Anatase is a form of Titanium Dioxide, usually found as brown crystals, used as a pigment in paints and inks.  TiO2    It crystalizes in the Tetragonal system.  Named by Rene Just Hauy.  Thanks Wikipedia.

Anatase
This is a sample I've shown before:  Anatase_jones_mill_magnet_cove_arkansas.  Some of you might recognize it.  It's a new stack dated 9-19-19.

Anatase (same sample)
I had a viewer question me about the "electric blue" crystal beside of it.  I think this shot shows that the crystal is blue through and is therefore also Anatase.
